As a reputable, international law firm with a proud history, we feel a strong sense of responsibility for the development of a more sustainable society. This is why we ensure that CSR remains an integral part of our firm and culture and we have defined clear principals to support it.

Our CSR contribution to society is rooted in effective legal advice and relevant pro bono work. Further to these areas, we are investing in a diverse and inclusive culture in which talented people can thrive regardless of gender and ethnicity. To ensure we attract and nurture this talent, we strive to create a diverse, inclusive and supportive culture in all our offices throughout the world. To this end, we work closely with universities, recruitment agencies and student bodies to create opportunities for them.

Each year we handle a number of pro bono cases which either have a profound social significance, or that address a fundamental legal principle. They also frequently involve complex issues of civil, administrative or human rights law.

These cases are handled free of charge or at significantly reduced rates and we are proud that our lawyers invest their time and energy to assist those who would otherwise be unable to receive such counsel.

Every year, our partners and associates continue to play an active role in various pro bono matters, taking on cases that make a real difference to individuals, and local and national organisations.

We also take responsibility towards our own people. We provide all members of our firm with the environment and the facilities that encourage them to develop their full potential. We also offer flexible work solutions so they can combine their practice with family life. We invest heavily in the personal and professional development of our people.

We use our means and abilities towards the communities in which we work and live: we engage in social, cultural and scientific sponsorship, supporting our local communities.

We provide financial and in-kind sponsorship of organisations dedicated to academia, the arts and the wellbeing of children. We feel it is both our duty and our privilege to return something to the communities in which we operate. This is why we sponsor cultural events, scientific pursuits and children in need. We not only provide financial support, but also share our knowledge and practical support through our active board membership of several NGOs.

We strive to a more sustainable environment. We are minimising our environmental impact and reducing our carbon footprint by embracing new technologies and inspiring people to continuously make conscious decisions on whether their behaviour would best fit an environmentally friendly approach. We installed energy saving technology, encourage our people and clients to use public transport and use IT and telecommunication technology to reduce commuting. We reimburse public transport costs to encourage everyone to use it.

By investing in state-of-the-art archiving and a digital work environment, we significantly reduce our paper usage.

Our new office building in Amsterdam is CO² neutral and we received a BREEAM Excellent quality mark from the Dutch Green Building Council.

Together, we want to ensure the legal profession in general, and our firm in particular, continues to contribute to a sustainable society. We will pursue each of our CSR values with the same drive we bring to our legal advice.
